prompt "Endianness selection"

Some MIPS boards can be configured for either little or big endian
byte order. These modes require different U-Boot images. In general there
is one preferred byteorder for a particular system but some systems are
just as commonly used in the one or the other endianness.

help
Enable this option if you want U-Boot to hand over the Yamon-style
command line to the kernel. All bootargs will be prepared as argc/argv
compatible list. The argument count (argc) is stored in register $a0.
The address of the argument list (argv) is stored in register $a1.
config MIPS_BOOT_ENV_LEGACY
bool "Hand over legacy environment to Linux kernel"
default y
help
Enable this option if you want U-Boot to hand over the Yamon-style
environment to the kernel. Information like memory size, initrd
address and size will be prepared as zero-terminated key/value list.
The address of the enviroment is stored in register $a2.

help
Enable this option if you want U-Boot to hand over a flattened
device tree to the kernel.
Note: the final hand over to the kernel is not yet implemented. After
the community agreed on the MIPS boot interface for device trees,
the corresponding code will be added.
